We can only deprecate CS this one time.  If ISO 3166/MA re-reused it, 
for a reunified Serbia and Montenegro or any other entity, we would have 
to press a UN M.49 3-digit code element into service as a region subtag. 
We did that on purpose.

In separate mails I will send the three necessary registration forms:

* to add region subtag RS
* to add region subtag ME
* to deprecate region subtag CS

Please note that CS will *not* have a Preferred-Value attached to it. 
This is exactly the same situation as for region subtags NT and SU.  It 
should be evident that neither "Serbia" nor "Montenegro" is a suitable 
replacement for "Serbia and Montenegro."
